0 all whom t may concern:

' Be it known that I, WALTER J BARRoN, citizen of the United States, andresident of the borough of Brooklyn, city of New York, in the. county ofKings and State of New York, have'inventedcertain new and usefulImprovements in TypeVVi'iting May chines, of which the following is aspecification.

My invention relates to indicating mechanisin and type bar repulsermechanism for typewriting machines.

VOne object of my-inventioii is to provide Y" improved indicatingdevices for indicatingv the printing-point on the platen, said devicesbeing simple in character and .near the printing point so that a closeadJustment may be obtained of any desired point on ther work sheet tothe printing point.

Another object of the invention is to provide improved repulser devicesfor coperating with the type bars when actuated to facilitate theirreturn from printing to nori ticularly pointed out in the claims.

` 'My invention is shown as applied to a No.

10v Remington typewriting machine but the nature of said invention issuch that it may readily be adapted to other styles of writing machines.

In the accompanying drawings illustrat-l ing one form of my invention,Figure 1 is a "fragmentary vertical front to rear sec' tional view of aNo. 10 Remington machine embodying my invention, parts of said ma- Ychine being omitted and parts broken away.

Fig. 2 is a fragmentary vertical transverse sectional view of some ofthe parts shown in Fig. 1 but showing one of the type bars in printingposition. Fig. 3 is a fragmentary front elevation of some of the partsshown 0 in Fig. 2. Fig. 4 is a fragmentary front view on an enlargedscale showing the relationship between the indicating device and theprinting point in the shifted position of the platen.

As shown in Fig. 1 the main frame of the lift the shift frame andelevate'- l frame and platen to receive imprints from machine comprisesay base portion l from which rise posts 2 supporting atop plate 3. Keylevers 4 are fulcrumed on a lplate 5, each key lever being connected bya link v(i, lever? and second link 8 to a type bar 9.

The type bars are pivoted at 10 to hangers secured to a stationarysupport 11. The free ends of the type bars normally rest on a stationarysupport 12. Each typefb'ar carries a type block 13 which is providedwith two types 14 and 15, the former being a small and 'the latter acapitallettcr.'` Betweenvthe types on each type blockw is a depressionor space 16, the bottom of which is the face of the block proper.

Nhen the type bars are actuated the types are adapted to cooperate withthe front face of a rolleil platen17 pivotally'supported on a-platenframe comprisingend .bars 18 andiA a cross bar 19, said frame beingconnected by links or devices 2O to a carriageor truckl comprising endbars 21 and front and" rear bars 22. The bars 22 are oppositely groovedto receive anti-friction balls 23 whichy also cooperate with fixed guiderails 24. The truck and platen framev compose a carriage for the platen,which carriage is impelled leftward by the usual spring drum', (notshown), the leftward or printi'ng move' ments being controlled by-escapement devices of the usual or any suitable pattern' which areconnected by a link 25 with an arm 2G fixed to a rock shaft 27 mountedinthe base 1. vFixed to said rock shaft near its ends are arms 28 fromwhich depend 'Patented apr. 23, 1912.

and 3 oinprisesf'an upright portion 44e having an angula'rly disposedinwardly bent portin'k tatthe upper end, the lower end of thefiiprightportion/14 terminating a loopet. The 'loop 46 receives a headed screw t7ywhich 'engages a tapped hole in the meinberel at the'top 4of theright-hand arm 42and detachably secures the indicating device toitssupport.4 -The arnol orporton 44e extends upward transversely of theprintVr ing linel (represented in Fig. 2 by the letters Z, n) is offsetor bent rearward abovefthe screw/4( sol as to lieclcse to the face ofthecard/guide, but, the portion t5 is clear otV the cardguide, so thatnothing is interposed betwieen lo and the platen save the pjapei. Theportion 45 extends lengthwise of theiplaten and' of the printing lineand above said printing line, terminato ing over the printing'point but,in line therewith. V"In other Words, the inner or left-handfend, 'oredge of the part 45 is di? rectly over 'theaniddle of the small lettern,

which asshown is overlying the printing point so that a line transverseot the printing line and at right angles 'thereto and passing throughthe printing point' will also containthe end or edge of the portion fio.Suc-hpa line is the broken line in yFig. I, designated by the referenceimmoral 48. The lotteria in Fig. 8 is in the line above the printingline. It will ho observed that the pointer isclosc to and iu thc samevertical vline as .the printing point, so thatany desired portion of thework sheet'nlay be readily'brought to thc printing point be causent thefacility with which the. printing point may bellocatcd. by means ot' thepointer. lt will further be observed that the pointer or indicatingdevice is on a relatively stationary part ofthe machine which docs notmove during printing operations; Fu rthcrinore,` thc pointer" is on asupport which shi.. i with .the platen so that the pointerv always;hearsthe saiuc'nornial rc latfionshil'i with the plat'en in uppercase aswell'fas iii-lowercase. This will be under- .stood'niore especially"from Fig. "/t which .force'it toward thepplaten to shifted positionwith the capital letter N overlying the printing point. v The indicatingdevice or finger is preferably made of spring metal as above stated andthe horizontal portion.K L tnormally stands slightly away from theprinting face of the platen as shown in Fig. l. This portion is solocated that when a type bar is actuated the types 14 and 15 thereonwill pass at opposite sides above and below the portion 45 which willengage the space or opening lt' between and separating said types, J ustprior to the printingmoment the tace ol the type block 13 between thetypes will engage the portion 45 and will shown in Fig. f2,l therebyflexing somewhat the inner or r'ree portion of the ar'in 45, theopposite end 'of which will be forcibly' pressed against the card guide;Consequently when the actuated key lever is released' the spring in thearm or portion l5 ot' the indicating device serves to assist the keylever spring 4f) in restoring the type bar to normal position, the typebar receiv ing its initial in'ipulse away from the platen fronitheindicating device which thus serves as a rcpulser. y

lt will be observed that the repulser cooperates with thetype bar at thefarthest practicable point from 4the pivot thereof, which is the mosteliiective point for coperation. In other words, a slight impulsecommunicated to the outer cud of the type bar will be more effectivethan a considerthe position ably greater impulse communicated near. i

the type bar pifvot would be.

it will be noted further that the detachable spring finger hereindescribed is siniple and inexpensive in construction. may be appliedwithout altering the machine in any respect, and provides an effectivepointer or indicator for the printing point ou thc platen and also anellectlve repulscr for tho typo bars, ynfcventing blurring and promotingthe speed or' the typebars at the start ol their return movon'lents.

Various changes may be' made without departing -from the scope of myinvention.
